Hi what I was actually looking for, was the reason this error was happening, after a snap remove.
So I found there was still a directory /snap/skrooge sudo rm -r skrooge, then close terminal, reopen and skrooge instantiates from deb install.
The deb install of skrooge is missing a whole bunch of icons, and does not work properly. This is a separate issue and Ive raised a bug report with KDE. When its sorted, I’ll complete this thread by commenting whats needed to bring in the missing icons.
As for your question I needed to be able to instantiate skrooge from terminal to see what errors were causing the errant operation.
Skrooge error (missing icons) I fixed by:
sudo apt-get install breeze-icon-theme
